Abstract

Described is a method as well as an apparatus for incineration of combustible waste during the manufacture of cement clinker by which method the waste is introduced via a waste inlet (11) and supported on a supporting surface (21) incorporated in a separate compartment (9), where the waste being actively transported, while simultaneously subjected to incineration, through the compartment to its outlet (23), where the hot exhaust gases produced in connection with the incineration of the waste being vented to the preheater system for heating the cement raw meal, and where the slag generated during the waste incineration process being extracted from the compartment (9). The method and the apparatus are peculiar in that exhaust gases containing NOx are introduced to the compartment (9).

Claims (14)

1. Method for incineration of combustible waste during the manufacture of cement clinker where cement raw meal is preheated in a preheater system (1) with or without a calciner (3), burned into clinker in a kiln (5) and cooled in a subsequent clinker cooler (7), by which method the waste is introduced via a waste inlet (11) and supported on a supporting surface (21) incorporated in a separate compartment (9), where the waste being actively transported, while simultaneously subjected to incineration, through the compartment to its outlet (23), where the hot exhaust gases produced in connection with the incineration of the waste being vented to the preheater system for heating the cement raw meal, and where the slag generated during the waste incineration process being extracted from the compartment (9), characterized in that exhaust gases containing NO x are introduced to the compartment (9).
2. Method according to claim 1, characterized in that at least a part of the incineration of the waste in the compartment takes place in a sub-stoichiometric atmosphere.
3. Method according to claim 1 or 2, characterized in that exhaust gases from the kiln (5) are introduced to the compartment via a riser duct (6).
4. Method according to claim 3, characterized in that all exhaust gases from the kiln are introduced to the compartment.
5. Method according to any of the claim 1 to 4, characterized in that the waste is transported through the compartment (9) to its outlet (23) along a circular path
6. Method according to any of the claim 1 to 5, characterized in that the exhaust gases are introduced into and through the compartment (9) in counterflow to the waste stream.
7. Method according to any of the Claim 1 to 6, characterized in that cement raw meal is introduced to the riser duct (6) via an inlet (12).
8. Method according to any of the Claim 1 to 7, characterized in that cement raw meal is introduced to the compartment (9) via an inlet (13).
9. Method according to any of the Claim 1 to 8, characterized in that hot air from the clinker cooler (7) is introduced to the compartment (9).
10. Method according Claim 1, characterized in that the exhaust gases generated during the waste incineration process are fed to the calciner (3) of the preheater (1) for calcination of the cement raw meal.
11. Method according claim 1, characterized in that the slag produced during the waste incineration process as well as any unburned waste are discharged from the compartment (9) at its outlet (23) and into the kiln.
12. An apparatus for incineration of combustible waste comprising a raw meal store (17), a preheater system (1) with or without calciner (3), a kiln (5), a clinker cooler (7), a compartment (9) for incineration of the waste, said compartment comprising an inlet (11) for introducing the waste into the compartment (9) and an outlet (23) for diverting slag and any unburned waste, which compartment (9) comprises also a supporting surface (21) for supporting the waste during the incineration process and means (21, 31) for transporting the waste from the waste inlet (11) of the compartment to the outlet (23), characterized in that it comprises means for introducing exhaust gases containing NO x into the compartment (9).
13. Apparatus according to claim 12, characterized in that the means for introducing exhaust gases into the compartment (9) comprises a riser duct (6), which is connected to the kiln (5).
14. Apparatus according to claim 12, characterized in that the supporting surface (21) is substantially horizontal.
